World-line approach to the Bern-Kosower formalism in two-loop Yang-Mills theory
Haru-Tada Sato, Michael G. Schmidt
Based on the world-line formalism with a sewing method, we derive the Yang-Mills effective action in a form useful to generate the Bern-Kosower-type master formulae for gluon scatt…
SUSY Variants of the Electroweak Phase Transition
Stephan J. Huber, Michael G. Schmidt
The MSSM with a light right-handed stop and supersymmetric models with a singlet whose vev is comparable to that of the SU(2)_W Higgs allow for a strongly first-order electroweak p…
World Line Path Integrals as a Calculational Tool in Quantum Field Theory
Michael G. Schmidt, Christian Schubert
We report on the status of the string-inspired world line path integral formalism, a recently developed powerful tool for the reorganisation of standard perturbative amplitudes in…
Exact Combinatorics of Bern-Kosower-type Amplitudes for Two-Loop Theory
Haru-Tada Sato, Michael G. Schmidt
Counting the contribution rate of a world-line formula to Feynman diagrams in theory, we explain the idea how to determine precise combinatorics of Bern-Kosower-like amplitud…
